a(x+b)=4x+10 in the equation above a and b are constants. if the equation has infinitely many solutions for X, what is the value

xeze [42]

Answer:

$b= \frac{5}{2}$

Step-by-step explanation:

Given

$a(x+b)=4x+10\\ax+b= 4x+10\\$

Now we know that system has infinite solution for x

$\frac{a_1}{a_2}=\frac{b_1}{b_2}$

in above equation.

$a_1=a, a_2=4, b_1=ab,b_2=10\\$

∴ $\frac{a}{4}=\frac{ab}{10}\\\therefore b=\frac{10\times a}{4\times a}=\frac{5}{2}$

What is the solution of the equation?-10 + sqrt x+8 = -4

pantera1 [17]

$D:x+8\geq0\to x\geq-8\\\\-10+\sqrt{x+8}=-4\ \ \ /+10\\\\\sqrt{x+8}=-4+10\\\\\sqrt{x+8}=6\iff x+8=36\\\\x=36-8\\\\x=28\in D$
